光被一些人定义为能够刺激视网膜并产生视觉感觉的辐射能。”对于人类来说,这有效地将光的光谱范围定义为彩虹的光谱范围,即波长约为360至830纳米(nm)。*彩虹产生的视觉感觉是颜色(色调)和亮度的一种,但光买卖的法律和技术标准有效地只承认与之相关的亮度。这些标准不承认紫外线(UV)辐射,在自然光环境中,紫外线的波长约为290纳米。也没有任何关于光的时间规范,光的开关阶段之间的转换,或者光的周期性曝光。从290纳米到830纳米的所有波长的辐射及其时间变化都可能产生医学或生物效应,这一事实表明,有必要审查当今工业化国家大多数人工作时使用的自然光和人造光之间的差异。因此,本文提供了波长290- 830nm的自然光和人造光的基本数据,并/或参考了这些数据,由此可以推导出其他相关的辐射学、光度学、比色学、时间学和生物统计学数据。在定义光和限制产生光的能源消耗的现有标准和法律的背景下给出并讨论了这些例子。
Light is defined by some as radiant energy that is capable of exciting the retina and producing a visual sensation.' For humans this effectively defines the spectral range of light as that of the rainbow, that is, wavelengths of about 360 to 830 nanometers (nm).* The visual sensation produced by the rainbow is one of both color (hue) and brightness, but the legal and technical standards by which light is bought and sold effectively recognize only the brightness related s t imul~s .~" The standards do not recognize ultraviolet (UV) radiation, which extends to wavelengths of about 290 nm in the natural light environment. Nor is there any specification for time in relation to light, the transition between on and off phases of light, or the periodicity of light exposure. The fact that radiation of all wavelengths from 290 nm to 830 nm, as well as its time variations, can have medical or biological effects suggests the need for a review of the differences between natural light and artificial light under which most people in industralized countries are working today. Accordingly, in this paper basic data are presented, and/or referenced, for natural and artificial light of wavelength 290-830 nm from which other related radiometric, photometric, colorimetric, chronometric, and biometric data of interest can be derived. Examples of these are given and discussed in the context of existing standards and laws defining light and limiting energy consumption for generating it.
